A number of promising biologic therapies are beginning to transform the treatment of adult patients with acute lymphoblastic leukemia, with the greatest potential seen with blinatumomab and inotuzumab ozogamicin in combination with chemotherapy, according to a presentation by Hagop M. Kantarjian, MD, at the 37th Annual CFS.<br /> &nbsp;

Treatment targeting molecular pathways such as <em>BRAF, </em>HER2<em>,</em> and <em>RAS</em> has typically been reserved for later lines of therapy for patients with metastatic colorectal cancer. Benjamin A. Weinberg, MD, said that agents targeting these pathways are not yet ready for the upfront setting, but data from ongoing trials suggest that these agents may eventually have a role to play in first- and second-line treatment.

Immunotherapeutic agents have grown in popularity for treating mismatch repair&ndash;deficient metastatic colorectal cancer, becoming the standard of care in the second line, Howard Hochster, MD, told an audience at the 2019 Gastrointestinal Oncology Conference. Furthermore, ongoing clinical trials suggest that these agents may play a larger role in treating CRC going forward.

What is the ideal first-line therapy for nonresectable, non&ndash;transplantable eligible, liver-only hepatocellular carcinoma? In a debate at the 2019 Gastrointestinal Oncology Conference, Mark Yarchoan, MD, had the unenviable task of convincing the audience that systemic therapy was the way to go.

The FOLFIRINOX regimen remains the treatment of choice for patients with pancreatic cancer even as clinical trials exploring potential therapies, including CD40 and CPI-613, offer the possibility of new options for a notoriously difficult-to-treat disease, Davendra P.S. Sohal, MD, MPH, told an audience at the 2019 Gastrointestinal Oncology Conference.

In the phase III ATTRACTION-3 study, nivolumab prolonged overall survival compared with chemotherapy in patients with previously treated advanced esophageal squamous cell carcinoma, according to findings presented at the 2019 ESMO Congress.

CDK4/6 inhibitor&nbsp;abemaciclib plus endocrine therapy led to significant benefits in a population of predominantly Chinese women with advanced&nbsp;hormone receptor&ndash;positive/HER2-negative breast cancer, according to data from 2 randomized trials presented at the 2019 ESMO Congress.

In the phase III PROfound trial, olaparib improved radiographic progression-free survival compared to either abiraterone acetate or enzalutamide in men with heavily pretreated metastatic castration-resistant prostate cancer, who had homologous recombination repair gene alterations, according to findings presented at the 2019 ESMO Congress.&nbsp;

Strong objective responses rates were seen in the phase I/II LIBRETTO trial, which studied RET inhibition with selpercatinib in patients with&nbsp;<em>RET</em>-mutant medullary thyroid cancer and for those with other&nbsp;<em>RET</em>&nbsp;fusion-positive thyroid cancer. The registrational findings were recently presented at ESMO Congress 2019.

Results from the phase III MONARCH 2 trial showed that the addition of the CDK4/6 inhibitor abemaciclib to fulvestrant improved overall survival by 9.4 months compared with fulvestrant and placebo in patients with hormone receptor&ndash;positive, HER2-negative advanced breast cancer who progressed on prior endocrine therapy, according to data presented at the 2019 ESMO Congress.

A subgroup of patients with triple-negative breast cancer who had immune cell PD-L1 expression, by the SP142 immunohistochemistry assay had responses to atezolizumab and nab-paclitaxel, regardless of whether they had primary or metastatic disease, according to an exploratory biomarker substudy of IMpassion130.

Patients with advanced hormone receptor&ndash;positive, HER2-positive breast cancer had improved progression-free survival when receiving the CDK4/6 inhibitor abemaciclib and endocrine therapy with trastuzumab compared with trastuzumab and chemotherapy, according to findings from the randomized phase II monarcHER trial.<sup>1</sup>

A randomized phase II study with patients with metastatic triple-negative breast cancer showed unexpected improved overall survival with the addition of trilaciclib, an investigational CDK4/6 inhibitor, to gemcitabine and cisplatin, even though the combination failed to meet a safety-related primary endpoint.
